Objectives : This study seeks to grasp the current status of Koryo medical research in North Korea, by focusing on researchers and research topics. Methods : A network analysis of co-authors and keyword which were extracted from Koryo Medicine - a North Korean traditional medicine journal, was conducted. Results : The results of author network analysis was a sparse network due to the low correlation between authors. The domain-wide network density of co-authors was 0.001, with a diameter of 14, average distance between nodes 4.029, and average binding coefficient 0.029. The results of the keyword network analysis showed the keyword "traditional medicine" had the strongest correlation weight of 228. Other keywords with high correlation weight was common acupuncture (84) and intradermal acupuncture(80). Conclusions : Although the co-authors of the Koryo Medicine did not have a high correlation with each other, they were able to identify key researchers considered important for each major sub-network. In addition, the keywords of the Koryo Medicine journals had a very high linkage to herbal medicines.

Objectives : Medical treating with eating foods is one of important therapies in East Asian traditional medical knowledge and is referred as a therapy to treat diseases through foods. Since the food cannot be separated from ordinary people living, the medical treating with eating foods is a therapy with strong locality and contains many autogenous parts. Methods : Recently, the world is showing much interest for genetic resources, and the concept of intellectual property is rapidly expanding as the field of 'new knowledge property right' as well. Thus, the knowledge of medical treating with eating foods recently draws much attention in the economic aspect beyond the scholarly interest for traditional medicine. Here, I would like to summarize and report the contents related to medical treating with eating foods on "Yi, SeikKan experience prescriptions" which was discovered before. Results & Conclusions : First, medical treating with eating porridge on "Yi, SeikKan experience prescriptions" is classified into one with nonglutinous rice as the main ingredient and the other with other grains as the main ingredient. It is differently utilized depending on the nature of the grain. Second, medical treating with eating rice on "Yi, SeikKan experience prescriptions" was born from our nation's unique way of living and is classified into one way to eat rice mixed with ground medicinal herbs, another one to cook and eat rice with mixed grains and the other way to use as the external application. Medical treating with eating rice is assumed to replace the meal. Third, "food section" was given separately and discussed in this book. There were some parts different from existing medical knowledge due to the accumulation of experience using medicinal herbs. Fourth, we should pay attention to experience a book on medicine where vibrant medical information has been recorded in order to discover and process our traditional knowledge resources as a useful form.

19-20세기 조선 의가들의 ‘『본초강목』 재구성하기’

오준호(Oh Junho) 한국의사학회 2013 한국의사학회지 Vol.26 No.2

There are three kinds of books written by different authors in different regions in the 19th century. These books include 『BonChoYuHam (本草類函)』 (1833), 『BonChoBuBangPyeonRam (本草附方便覽)』 (1855) and 『BonChoBang (本草方)』 (1860?). However, these books are very similar in terms of content and format. They were written in the format of large medical books and they contained prescriptions made up with 1-2 kinds of herbals depending on diseases. These three books which could not affect each other appear to have these commons. The reason is that these books were newly edited based on Bubang (附方) in 『BenChaoGangMu』 depending on diseases and 『BenChaoWanFangZhenXien』 (1712) written by Cai, lie Xian (蔡烈先) was used as the reference. Woodblock printed book of 『BenChaoGangMu』 viewed by medical practitioners in Joseon Dynasty in the 19th century mostly had 『BonChoManBangChimSun』 which could be called ‘『BenChaoGangMu』 Bubang index’ as the appendix. All authors of three books tried to make ‘reorganization of 『BenChaoGangMu』’ by using 『BonChoManBangChimSun』 as the important reference. Work of ‘reorganization of 『BenChaoGangMu』’ focusing on symptoms being made in the 19th century was made a few times in the 20th century. 『YangMuSinPyeon』 and 『SuSeBiGyeol』 published in 1928 were outcomes of these works in the 20th century. ‘Reorganization of 『BenChaoGangMu』’ being made in 19th-20th centuries showed great interest for 『BenChaoGangMu』 in the medical community in the late Joseon Dynasty. In addition, the practical scholarship of Joseon Dynasty gave 『BenChaoGangMu』 the value as the collection of prescriptions rather than the concept of book for herbal medicine. Prescriptions of reorganized 『BenChaoGangMu』 have been spread out to many books in the late Joseon Dynasty. Thus, the impact of 『BenChaoGangMu』 on society in the late Joseon Dynasty seems to be much larger than what has been known so far.

탄소 중립 운동의 가속화에 따라서 기존 화석연료에서 무탄소 연료 전환을 바탕으로 친환경 모빌리티를 개발하기 위한 연구가 활발해지고 있다. 이러한 관점에서 친환경 특성을 갖는 수소 연료가 모빌리티 산업의 차세대 핵심 연료로 각광받게 되었으며 최근 수소 연료전지 기술이 상용화 차량에 적용되어 출시됨에 따라 친환경 차량으로서 많은 주목을 받았다. 그러나, 연료 전지의 높은 제조 비용과 낮은 내구성이 문제점으로 거론되기 시작했다. 이에 미래 수소 경제 실현을 위한 가교 역할로서 수소 연료 내연기관으로 관심이 옮겨지고 있다. 수소 내연기관은 기존 내연기관에서 소량의 부품 변경만으로도 구현이 가능하므로 현재 사용되는 생산 기술 및 인프라를 유지할 수 있으므로 높은 신뢰도와 저렴한 가격으로 도입이 가능하다는 측면에서 연료 전지 대비 강력한 이점을 갖는다. 그러나, 수소 내연기관이 상용화 단계에 도달하기 위해서는 수소 연료의 낮은 인화점으로 인해 발생하는 역화 혹은 조기점화와 같은 비정상 연소와 기존 가솔린 엔진과 비교하여 낮은 출력 특성을 개선할 필요가 있다. 본 연구는 수소의 연소적인 측면에서 비정상 연소 개선 및 출력 특성 향상을 위해 연료 분사 전략에 따른 연소 및 배기 경향을 실험실 단위에서 분석하였다. 실험에는 2L 급 상용 전기점화 엔진이 사용되었으며 엔진 속도 1,500 RPM 에서 포트 분사 및 직접 분사 방식을 각각 비교 실험하여 엔진 단위에서 출력 향상을 위한 연료 분사 전략을 검토하였다. 포트 분사의 경우 연료 공급량 증가에 따라 최대 출력이 늘어났으나 수소가 흡기 공기의 체적을 대체하여 농후한 조건의 혼합기가 형성됨에 따라 비정상 연소 가능성이 증가하고 열전달 손실 증가로 인해 제동열효율이 저감되는 것을 확인했다. 직접 분사의 경우 연료 분사 시기를 350 BTDC CA에서 지각하여 실험을 진행했으며 분사시기가 지각될수록 흡입 공기량이 증가하여 희박한 혼합기가 형성되었다. 이에 따라 제동열효율이 증가하고 엔진 출력이 함께 증가하는 것을 확인했으며 희박 연소 조건에서 질소산화물 저감을 통한 배기 특성 개선이 확인되었다.

Objectives : The purpose of this study is to help select an appropriate word embedding method when analyzing East Asian traditional medicine texts as data. Methods : Based on prescription data that imply traditional methods in traditional East Asian medicine, we have examined 4 count-based word embedding and 2 prediction-based word embedding methods. In order to intuitively compare these word embedding methods, we proposed a "prescription generating game" and compared its results with those from the application of the 6 methods. Results : When the adjacent vectors are extracted, the count-based word embedding method derives the main herbs that are frequently used in conjunction with each other. On the other hand, in the prediction-based word embedding method, the synonyms of the herbs were derived. Conclusions : Counting based word embedding methods seems to be more effective than prediction-based word embedding methods in analyzing the use of domesticated herbs. Among count-based word embedding methods, the TF-vector method tends to exaggerate the frequency effect, and hence the TF-IDF vector or co-word vector may be a more reasonable choice. Also, the t-score vector may be recommended in search for unusual information that could not be found in frequency. On the other hand, prediction-based embedding seems to be effective when deriving the bases of similar meanings in context.

한의학지식정보자원 DB구축에 있어서 지식고고학적 가중치부여의 의의와 실제적용방안 연구

It is the well-known truth that processing of raw information is needed to a certain extent during information search. Especially for Oriental Medical information, it becomes much clearer that even more complex processing is necessary. As a means of reducing such complexity, this study suggests a way to understand effectively the organic relationships among information found on the interface. In this process, 'knowledge-based archaeological' method has been used. A new concept of interface observed by this research is the study of a system which contains realistically considered knowledge-based archaeological and historical specificity. These models are organized so that search results could be materialized in different tree-structured interface models, which can help one understand the relationships among wanted search results at one glance and confirm the details of those results via mouse click. Strength of the vertical tree structure resides in its capability of suggesting its users clear historical relationship between separate Oriental medical information. The horizontal tree structure enables deeper understanding of sectional interrelationship of searched information. The strength of the prescription tree structure is that it helps one understand the lineage of prescriptions, as Oriental medicinal treatment is often summarized into changes in prescriptions.

Objectives : The purpose of this study is to compare the similarities among Donguibogam(DO), Uihagibmun(UI), and Gyeongagjeonseo(GY) in order to examine whether the medical thoughts embedded in the texts can be compared in a quantitative way. Methods : Under an empirical assumption that medical thoughts can be reduced to the frequency of major key words within the text, we selected the fourteen words of the four categories that are commonly used to describe physiology and pathology in Korean medicine as key words. And the frequency of these key words was measured and compared with each other in the three important medical texts in Korea. Results : As a result of quantitative analysis based on χ2 statistic, the key words in the books were distributed most heterogeneously in DO and distributed most homogeneously in UI. In comparison of the similarity analyzed by the same method, DO and UI were significantly more similar than those of DO and UI. The results of the word frequency pattern and the similarities of the book contents(CBDF) show that DO is influenced by UI, and the differences between standardized residuals and homogeneity tells us that internal context of both books are constructed differently. Conclusions : These results support the results of traditional research by experts. With the above, we were able to confirm that medical thoughts can be reduced to the frequency of major key words within the text, and compared through the frequency of such key words.

On Whom You Spend, There Your Ethics Will Be: The Combined Effect of Spending and Construal Level on Ethical Behavior

Junho Oh(오준호),Su Sang Lee,Yunchul Shin,Jessica Seungyoon Sung,Sujin Lee 한국인사조직학회 2018 한국인사ㆍ조직학회 발표논문집 Vol.2018 No.1

Prior research has documented the strong link between money and unethicality. Our research extends previous findings by focusing on a different aspect of money: spending behavior, or on whom the money is spent. The current study integrates the spending literature and the construal level perspective to propose that individuals’ ethical behavior is determined by whom they spend their money on (the self or others) and how they think (abstractly/high-level or concretely/low-level). Experimental data show that under a high-level construal, people who spent money on others behaved more ethically than those who spent money on themselves. Under a low-level construal, however, neither prosocial nor personal spending influenced subsequent behavior related to an ethical dilemma. Thus, while people spend money on others, they should adopt an abstract, high-level construal to maintain greater integrity with regard to subsequent ethical dilemmas.
